"How exactly the "production" of bitcoin can slow down, when the network automatically adjusts to keep the "production" exactly the same average of 10 mins/block??? That is the whole point of the dynamic adjustment, that you can NOT increase or decrease coin generation in the long time/large scale, no matter how many trillion-billion-fillion hashes you add.
We could mine the same coins with 2 laptops. Or we could mine them with turning the Moon into a gigantic ASIC (cooling is kinda cheap in space). They would generate the same amount of coins after the 1st difficulty adjustment.
Radiant only, no air, much weird radiation, possibly scorching sun.
Prohibitively expensive
Edit:
